摘要
能效状态评估的关键是建立合适的评估指标体系与评估模型。对影响电力客户用电能效因素进行分类共性分析,将能效评估的指标体系划分为三层,包含经济能效、电能信息、生产信息及电能污染四类指标。基于模糊综合评判原理,对状态因素集、评判集、权重系数进行分析,结合指标体系建立了能效评估模型。在实例分析中,评估结果保留了各层评价指标的全部信息,并能转化为分值排序,这有助于电力企业直观了解电力客户能效状态。提出一套基于J2EE三层架构能效评估系统设计方案,对现代能效管理具有理论意义和实际参考价值。
The key of energy efficiency assessment is to establish appropriate evaluation index system and evaluation model. The paper analyzes the electric energy efficiency factors of customers,and classifies into three layers by evaluation index system of energy efficiency, including economic efficiency, energy information, production information, energy pollution and so on. R establishes evaluation model of energy efficiency by state factor set, evaluation set, the weight coefficient and the principle of fuzzy comprehensive evaluation. The assessment result through case analysis retains all the information of each index and is easily convened to score sort, which helps power enterprise to understand vividly energy efficiency of state electricity customers. Finally, the paper proposes a three-tier architecture design of energy efficiency rating assessment system（EERAS） based on J2EE, which is a meaningful way to modem energy management.
